HOPLONYX PERFORATUS, n. Sp. 



Black, quite opaque on the upper side and also on the under side, 

 but the legs are shining ; antennae piceous ; eyes very slanting in the 

 apical part, nearly transverse in the anterior, and therefore broadly 

 separated on the vertex, but much less so in the anterior part where 

 the intervening space is about one-third of their length, this space is 

 roughly punctate and has a plain, median, longitudinal groove, the 

 anterior part of the head is very slightly punctate ; prothorax slightly 

 attenuate laterally in front, from the very little rounded median part, 

 .and also slightly sinuate in the posterior, not much broader than 

 long, faintly impressed longitudinally in the centre, and covered with 

 somewhat irregularly scattered, deep, round punctures, base deeply 

 bi-sinuate ; elytra wider at the base than the prothorax and with the 

 humeral angles slightly oblique, gradually accuminate thence to the 

 apex, deeply striate with the intervals tectiform from the base to 

 three-fifths of the length, and having on the sharp edge a row of fine, 

 remote granules, strige filled with deep, scabrose punctures deeper in 

 the anterior part. 



Very closely allied to H. clypeatus, Fahr., which I have recorded 

 from the neighbourhood of the Zambesi Eiver and also from 

 Ovampoland ; the difference between the two consists in the 

 punctuation of the prothorax, which is extremely coarse and 

 scrobiculate in H. clypeatus, and comparatively shallow and with 

 smooth intervals in H. perforatus ; the elytral costae are also less 

 .acute than in H. clypeatns. 



Length 13 mm. ; width 6 mm.

HOPLONYX EXTRANEUS, n. sp. 



Black, opaque, glabrous, terminal joints of antennae and palpi sub- 

 ferruginous ; head closely and somewhat finely punctate, space 

 between the apex of the eyes slighter broader than half their width, 

 antennal crest strong ; prothorax one-third wider than long, plainly 

 rounded laterally in the anterior part near the apex, parallel thence 

 and carinate, not much convex, and covered with closely set, but not 

 quite contiguous, somewhat fine punctures ; scutellum triangular, 

 punctate ; elytra nearly parallel from the base to the median part, 

 slightly ampliated past the middle, and acuminate in the posterior 

 part, striate, the striae shallow, and filled with small, round punctures 

 separated by an interval nearly equal to their own diameter, intervals 

 plane and filled with numerous, closely set punctures, replaced in
